Technical Field

The present invention relates to a method for enhancing combustion efficiency and an apparatus using the same, and more particularly, to a method for enhancing combustion efficiency of existing combustion apparatuses, such as boilers, engines, etc., and an apparatus using the same.

Background

The combustion releases energy, and human beings obtain power by learning to control the combustion, so that the living standard is continuously improved from the industrial revolution to the present. However, interest arises and disadvantages follow. In a living environment, the waste heat and waste gas emission is increased while the waste heat and waste gas emission is increased as large as a coal-fired generator and as small as an engine of a steam locomotive. Ideally, the combustion exhaust gas is preferably only water vapor and carbon dioxide, which is minimally harmful to the environment and human health. However, due to the aging of the machine, the composition of the fuel, the combustion environment, etc., the exhaust gas generated by the aforesaid devices often contains some incompletely combusted substances, such as Hydrocarbons (HC) and carbon monoxide (CO), and toxic exhaust gas, such as nitrogen oxides (NOx) and sulfur oxides (SOx). Furthermore, these exhaust gases may also entrain heavy metals or combine with airborne dust to form fine aerosols (commonly known as PM 2.5) that are harmful to the airways and lungs of the human body. If these devices are more efficient, less will be generated by complete combustion of these human and environmental harmful substances.

In addition to environmental and health concerns, the efficiency of plant combustion is also cost-dependent. For example, the heavy oil required to spend a year in a production line of a steel mill is estimated to be approximately one hundred million, eight thousand, or more. If the cost can be reduced by 8-20% in this part, 1 thousand 4 hundred and so on, and ten thousand and 3 thousand and 6 million and so on can be saved for enterprises in the future in one year. In the micro-profit era, the growth of the enterprise revenue is more than multiple. Therefore, how to enhance the combustion efficiency has been the focus of the related industries.

Detailed Description

The technical solution in the embodiments of the present invention is clearly and completely described below with reference to the drawings in the embodiments of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

The present invention will be more specifically described with reference to the following embodiments.

Referring to fig. 1, a flowchart of a method for enhancing combustion efficiency according to an embodiment of the invention is shown. Here, the enhanced combustion efficiency is to allow the fuel to be combusted more completely without changing the supply of combustion air (e.g., air compression to increase the oxygen content per unit volume), closer to the goal of the elements being water and carbon dioxide after combustion. The method first provides a catalytic combustion improver (S01). The catalytic combustion improver is the core element of the method, and the components and the application of the catalytic combustion improver are explained below.

Overall, through numerous tests and modifications of the mixture ratio, the catalytic combustion improver comprises the following components: 0.9 to 1.1 parts by weight of titanium dioxide (TiO 2); 68 to 72 parts by weight of ethylene glycol; 21 to 25 parts by weight of Water (Water); 1.8 to 2.2 parts by weight of a surfactant; and 3.6 to 4.4 parts by weight of Zeolite powder (Zeolite). One preferred embodiment is titanium dioxide 1 part by weight, ethylene glycol 70 parts by weight, water 23 parts by weight, surfactant 2 parts by weight, and zeolite powder 4 parts by weight. Other proportions of the formula, as long as they fall within the aforementioned range, can achieve the purpose of enhancing combustion efficiency and are claimed by the present invention. Preferably, Sodium lauryl Sulfate (Sodium Dodecyl Sulfate) is used as the surfactant.

Because the catalytic combustion improver has the components, the oxygen content can be increased when assisting the combustion of fuel (which can be solid, such as coal, can be liquid, such as heavy oil or gasoline, and even can be gaseous, such as natural gas), so that the combustion efficiency can be enhanced. The catalytic combustion improver increases the oxygen content to enhance the combustion efficiency mainly by the following actions.

First, negative oxygen action. The titanium dioxide is ㇐ photocatalyst atoms, after being irradiated by 380nm visible light in a combustion chamber (the visible light with 380nm is generated in general combustion), electron holes absorb energy to electrons (with negative electricity) in the atoms and pass through an energy gap of 3.2eV to a conductive band, and due to the action of photoreduction (Photo Reduction) of the electrons, the Oxygen is changed into negatively-charged Oxygen with high activity, namely active Oxygen (Activated Oxygen), and the holes (with positive electricity) left in situ (valence charge band) react (oxidize) with OH on the surface of the titanium dioxide to generate OH with high Oxidation because of the Photo Oxidation (Photo Oxidation) action (steam state) of the holes^-A free radical. Reactive OH group^-Free radicals and negatively charged, highly reactive oxygen species decompose organic species (hydrocarbons) and degrade them back into carbon dioxide and water.

Secondly, oxygen enrichment. The composition of air is mainly a mixture of 78% nitrogen, 21% oxygen and 1% rare gases and impurities. In a normal natural combustion state, the oxygen concentration is 21%. If the air with higher oxygen content than the natural state is used as the combustion air, the oxygen-enriched combustion is realized. The negative oxygen action shows that the negatively charged oxygen with high activity can be completely combusted with hydrocarbon and degraded into carbon dioxide and water, and the electrode plate effect (the electrolytic potential of water is 1.23V) reduces the water (in a steam state) into H⁺With OH^-And the cycle is repeated in this way. Experiments show that the oxygen content can be increased by 2-5%, which is called oxygen enrichment. In addition, the theoretical air requirement is reduced with the oxygen enrichment, and the flame temperature at the time of combustion can be raised. This is also a factor for enhancing the combustion efficiency.

And thirdly, filling the atomic empty track domain. The electron sequence of nitrogen is 7, and the description is made in a theoretical point of view. 1S2S2P should have 4 orbitals, 8 electrons in the second layer, while nitrogen contains 7 electrons (also 2 electrons in the first layer and 5 electrons in the second layer). However, in terms of the number of orbitals in the second layer, it should be stable until 8 electrons are reached, but 3 electrons are lost (so-called empty orbitals). The invention can fill the original empty rail area by utilizing the generated electrons, so that the nitrogen reaches a stable state and is not combined with oxygen, thereby reducing the probability of generating NOx. However, the present invention has the effect of oxygen enrichment, so that in addition to the mechanism of the air rail area, under the premise of sufficient oxygen, the air intake can be reduced, and the excessive nitrogen can be reduced, so as to improve the combustion efficiency.

Fourthly, far infrared ray decomposition. The catalytic combustion improver can generate far infrared rays while electrolyzing oxygen, generates friction by utilizing the characteristic of different expansion coefficients of carbon molecules, and further mildly decomposes and participates in combustion the coking and slagging in a combustion chamber so as to improve the combustion efficiency.

From the above description, it is clear that the function of the catalytic combustion improver is known. Thus, in order to optimize the use of the catalytic combustion improver, the second step of the method for enhancing the combustion efficiency proposed by the present invention is to atomize the catalytic combustion improver (S02). The atomization mode is a feasible mode, such as vibrating the liquid level of the catalytic combustion improver with high frequency to generate an atomization effect, atomizing by adopting a traditional atomization nozzle, or atomizing by utilizing a heating mode. The key point is that the catalytic combustion improver can be effectively dispersed in the air after being atomized. Then, the atomized catalytic combustion improver is mixed with air to form a mixed mist (S03). Finally, the mixed mist is guided into a combustion chamber to be combusted with a fuel, and the combustion temperature of the combustion chamber is maintained to be not lower than 300 ℃ (S04), the purpose of maintaining the combustion temperature to be not lower than 300 ℃ is to enable the titanium dioxide to smoothly perform the photocatalyst reaction under the nanometer structure.

In addition, the proportion between the dosage of the catalytic combustion improver and the dosage of the fuel falls within a specific proportion interval, namely the dosage of the catalytic combustion improver is limited to a certain extent, and the combustion efficiency cannot be enhanced if the dosage is too much or too little. As a result of the experiment, the specific ratio interval varies depending on the fuel. For example, if the fuel is heavy oil, the specific proportion interval is one liter of catalytic combustion improver for 5,040 liters to 6,560 liters of heavy oil; if the fuel is natural gas, the specific proportion interval is one liter of catalytic combustion improver used for natural gas at 5,040-6,560 ℃; if the fuel is coal, the specific proportion is one liter of catalytic combustion improver for 11.9-13.1 metric tons of coal.

The invention also provides equipment for enhancing the combustion efficiency. Please refer to fig. 2, which is a schematic diagram of an embodiment of the apparatus. The apparatus for enhancing combustion efficiency includes: a catalytic combustion improver groove 10, an atomization module 20, an air extraction module 30, a combustion chamber 40, a fuel groove 50, a catalytic combustion improver communicating pipe 12 connecting the catalytic combustion improver groove 10 and the atomization module 20, a conveying pipe 32 connecting the air extraction module 30 and the combustion chamber 40, and a fuel communicating pipe 52 connecting the fuel groove 50 and the combustion chamber 40.

The catalytic combustion improver tank 10, as the name implies, is used to hold a catalytic combustion improver 100. The flow of the catalytic combustion improver 100 may be by gravity or may be pressurized. The atomization module 20 is indirectly connected with the catalytic combustion improver groove 10 by a catalytic combustion improver communicating pipe 12. In fact, the two can also be directly connected. The atomization module 20 is used for atomizing the catalytic combustion improver 100 in the catalytic combustion improver tank 10 and mixing the atomized catalytic combustion improver with air to form a mixed mist. The atomizing module 20 may further include two elements: an advance control motor 22 and an atomizer 24. The injection control motor 22 can control the amount of the catalytic combustion improver 100 atomized per unit time, i.e. maintain the ratio of the amount of the catalytic combustion improver 100 to the amount of the fuel in the previous embodiment within a specific ratio interval. The atomizer 24 atomizes and moves the atomized catalytic combustion improver 100 toward an opening 32a of the transport gas pipe 32 by the negative pressure in the transport gas pipe 32, so as to mix with the air (thin hollow arrow) coming from the transport gas pipe 32 to form a mixed mist (cloud form near the opening 32 a).

The air extraction module 30 can be any device having negative pressure (e.g., an exhaust fan, a blower, an air inlet, etc.) and introduces the external air 120 (bold hollow arrow) of the device into the air pipe 32 for being delivered to the combustion chamber 40 to be combusted with the fuel 500. The delivery pipe 32 passes through the opening 32a to deliver the mixed mist 140 (thin hollow dotted arrow).

The combustion chamber 40 includes an air inlet 42, a fuel inlet 44, a combustion space 46 and an air outlet 48. The air inlet 42 is connected to the opening of the transmission air pipe 32 for receiving the mixed mist 140. The fuel inlet 44 is configured to receive fuel 500. In this example, the fuel 500 is received by the fuel communication pipe 52, and the flow of the fuel 500 is not limited to gravity or pressure. The combustion space 46 (shown in dashed lines) is where combustion occurs, where the fuel 500 and the mixed mist 140 are primarily mixed and then combusted. Of course, the more severe of what is referred to herein as combustion may be present in the form of an explosion. Exhaust port 48 may exhaust combusted exhaust gases 160 from combustion chamber 40. In practice, the combustion chamber 40 may be in the form of a boiler, an engine, or the like, which is operated by burning fuel.

As described in the previous embodiment, the combustion chamber 40 can maintain the combustion temperature at not less than 300 degrees Celsius. The ratio between the amount of catalytic combustion improver 100 and the amount of fuel 500 also falls within the specific ratio interval described above. The catalytic combustion improver 100 comprises: 0.9 to 1.1 parts by weight of titanium dioxide; 68 to 72 parts by weight of ethylene glycol; 21 to 25 parts by weight of water; 1.8 to 2.2 parts by weight of a surfactant; and 3.6 to 4.4 parts by weight of zeolite powder. The surfactant is preferably sodium lauryl sulfate.

The combustion efficiency enhancing apparatus disclosed in the above embodiments is applicable to internal combustion engines, such as the engines of vehicles; if the device is applied to an external combustion engine, such as a boiler, the elements of the device for enhancing the combustion efficiency may be changed as shown in fig. 3. In contrast to fig. 2, the transport gas tube 32 in fig. 3 has no opening 32a, and the atomizer 24 is no longer connected to the opening 32 a. Instead, the atomizer 24 opens directly into the upper extraction module 30, and the atomized catalytic combustion improver is mixed with the outside air 120 of the device by the extraction module 30 and then fed into the combustion chamber 40.

It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
